ANNAPOLIS, Md. — Thousands of Baltimore City families petitioned lawmakers for billions in funding to renovate or rebuild about 65 of the school district’s crumbling buildings. Parents, students, teachers and community leaders rallied in Annapolis Monday evening for legislation that would create a block grant each year in the state budget for the city’s schools, enabling the city to leverage that to borrow more money. Supporters say the measure would create more than $1 billion to remodel the dilapidated infrastructure of several schools. Legislation has been filed in Annapolis to create the program.
